As i main pally my self here is some tanking advice
When you pull with shiel loop use flash right after it , then start aggro combo you start by Fast blade > savage blade > flash > rage of halone . This combo will maximize your aggro and if the mobs are 5 or more you can switch target while attacking . Give every mob a kick , like fast blade on one mob *switch target* savage blade on another mob *switch target * flash > then rage of halone on the other target if u have casters in the party use flash after you finish the combo . Hope this helps .
